The invention provides an electronic vacuum pump control method and system and a storage medium, and the method comprises the steps: S10, obtaining the vacuum degree of an electronic vacuum pump in a current operation period, and controlling the electronic vacuum pump to be started when the vacuum degree is judged to reach a first starting threshold value, after the electronic vacuum pump is started, when it is judged that the vacuum degree reaches a first closing threshold value, the electronic vacuum pump is controlled to be closed; s20, whether the electronic vacuum pump is in a vacuum saturation state or not is judged according to the change gradient of the vacuum degree, if yes, S30 is executed, and if not, S10 is executed again; and S30, the first closing threshold value is updated and increased to be a second closing threshold value, and the first opening threshold value is updated and increased to be a second opening threshold value. Thus, the electronic vacuum pump can be controlled without installing an environment pressure sensor, the hardware cost is saved, it is guaranteed that opening and closing of the electronic vacuum pump can be dynamically controlled in different altitude environments, and then automobile braking safety in the different altitude environments is guaranteed.
本发明提供一种电子真空泵的控制方法及控制系统、存储介质,方法包括:S10:获取电子真空泵在当前的运行周期内的真空度,并在判断到真空度达到第一开启阈值时控制电子真空泵开启,以及在电子真空泵开启后判断到真空度达到第一关闭阈值时控制电子真空泵关闭;S20:根据真空度的变化梯度判断电子真空泵是否处于真空饱和状态,若是,则执行S30,若否,则返回执行S10;S30:将第一关闭阈值更新增大为第二关闭阈值,将第一开启阈值更新增大为第二开启阈值。如此,本发明不需要安装环境压力传感器便可实现对电子真空泵的控制,节省了硬件成本,保证在不同海拔环境下可动态控制电子真空泵的开闭,进而确保不同海拔环境下的汽车制动安全。
